Call to war! Twelve Plumed Spearmen arrive at your Home City Gather Point.
—In-game description

Inca Raiding Party is a Big Button technology in Age of Empires III: Definitive Edition that is unique to the Incas and can be researched at the Town Center once Inca Scouting Party is researched and the Fortress Age is reached. Once researched, 12 Plumed Spearmen will appear in the Home City shipment point. Inca War Party is the further upgrade of this technology.

This technology is cost-effective in terms of total resources. 12 Spearmen costing 1,200 food, 240 wood, total 1,440 resources versus the technology costing 1,200 total.

With the Industrial Age Old Ways Home City shipment, the cost is reduced to 300 food, 300 coin.
